Failed to Get Client (Peer) Certificate

[mfreds71]

I setup an HTTP Server using TaurusTLS 1.0.0.38 + OpenSSL 3.6.0 1 Oct 2025 + TLS1.3
Then I setup a MS.NET HTTP client, where I send requests with "digital certificado" ( X.509 ) from client.

But I can't get the certificate from the request, at server side, as:

function  _SSL_get_peer_certificate(const s: PSSL): PX509; cdecl;
begin
  Result := SSL_get1_peer_certificate(s);
end;

always retuns NIL

Does anyone knows how to fix that ?

Use the OnSSLNegotiated event. That has a TTaurusTLSIOHandlerSocket parameter.

You would do something like this:

ASender..SSLSocket.PeerCert

and access its properties.

HTH.
